Add cap blocks to the top row of a block or stone retaining wall. You can add a layer of masonry adhesive to hold them in place, then back fill. Or you can backfill as you go, then add the cap. Either way, it provides a nice finished look, much like edging added to a paver patio.
The Highland Stone® wall system is Eagle Bay’s most popular retaining wall for projects up to four feet. Its rough finish, visible on one side, blends seamlessly into its surroundings, especially when you use varying heights and widths.
